error[E0599]: the method `countx` exists for struct `Filter<Map<Repeat, for<'a> fn(&'a u64) -> &'a u64 {identity::<u64>}>, {closure@$DIR/hrtb-doesnt-borrow-self-2.rs:109:30: 109:37}>`, but its trait bounds were not satisfied
--> $DIR/hrtb-doesnt-borrow-self-2.rs:110:24

LL | pub struct Filter<S, F> {
| ----------------------- method `countx` not found for this struct because it doesn't satisfy `_: StreamExt`
...
LL | let count = filter.countx();
| ^^^^^^ method cannot be called due to unsatisfied trait bounds

note: the following trait bounds were not satisfied:
`&'a mut &Filter<Map<Repeat, for<'a> fn(&'a u64) -> &'a u64 {identity::<u64>}>, {closure@$DIR/hrtb-doesnt-borrow-self-2.rs:109:30: 109:37}>: Stream`

`&'a mut Filter<Map<Repeat, for<'a> fn(&'a u64) -> &'a u64 {identity::<u64>}>, {closure@$DIR/hrtb-doesnt-borrow-self-2.rs:109:30: 109:37}>: Stream`

LL | impl<T> StreamExt for T where for<'a> &'a mut T: Stream {}
| --------- - ^^^^^^ unsatisfied trait bound introduced here
= help: items from traits can only be used if the trait is implemented and in scope
note: `StreamExt` defines an item `countx`, perhaps you need to implement it

LL | pub trait StreamExt
